Partial-band interference due to intentional and unintentional jamming in fast frequency-hopping spread-spectrum (FFH/SS) systems can be effectively suppressed by additional signal processing techniques. The authors present the performance analysis of a binary frequency-shift-keying SS system in conjunction with a fast Fourier transform (FFT) processor. The FFT-based self-normalising receiver, requiring no knowledge of signal and jamming levels, also enjoys the advantages provided by modern digital signal processing technology. Numerical results show that the receiver performance is better than that of the square-law linear combining receiver and comparable to that of the conventional self-normalising receiver as well as the clipper receiver.
